What does the Glow-worm Energy F36 fault code mean?
The F36 fault code on a Glow-worm Energy boiler indicates a fault with the printed circuit board (PCB). This issue can disrupt the boiler’s operation, leading to heating and hot water failures.
Common Causes
- Electrical Short Circuit: A short circuit within the PCB can cause it to malfunction, resulting in the F36 error code.
- Component Failure: Failure of components on the PCB, such as capacitors or relays, can lead to this fault being displayed.
Can I fix it myself? (DIY)
It is highly recommended to call a Gas Safe Engineer for this issue, as working with the PCB involves electrical components that can be dangerous if handled improperly.
Estimated Repair Cost (2026 UK Prices)
The estimated repair cost for replacing a faulty PCB in a Glow-worm Energy boiler is around £250 to £350. This cost reflects the price of the part and the labour involved in installation.
